As someone who was a single parent from early 2015 until now, bringing up children who were all aged 10 and below, I can admit that there is stress with everything that you have to juggle, but if you get yourself into a routine and stick with that routine, it can help elimiate a lot of the stress many would go through who just try to juggle everything randomly.
My kids are all much older now and I have three that are adults and one that is about to be 17 in May, and as much as I have gone through some stress, it was never as much as I thought it would be with a solid routine in place.
